High-concerned chemical: none

Origin: Mainland China

Type: Module

8-channel digital interface bidirectional level-shifting module; the 1.8V side uses a level-shifting chip from TI.

The power input (VIN) on the B side can be connected directly to a 3.3V voltage source, or to a voltage of approximately 5V, which is then regulated to 3.3V by the on-board LDO.

Simply provide power to the B side to use the module; the 1.8V on the A side is generated by the on-board LDO to power the level-shifting chip’s A side.

This 1.8V power supply can also be used as an output to power downstream devices (note: avoid excessive power consumption!).

Additionally, please note that both sides must be grounded together. This means that the GND on the board connected to both the A and B pins must be connected to the GND on the level-shifting board; otherwise, waveforms or functionality may be affected.

Regarding the maximum supported conversion rates:

Maximum Data Rates

110 Mbps (Push-Pull Output)

1.2 Mbps (Open-Drain Output)

1. Supports level conversion for various interfaces, including 3.3V to 1.8V and vice versa (JTAG, SPI/I²C/UART/12S, GPIO/MP, etc.)

2. Also supports level conversion for the ADI SIGMA DSP emulator USBi (many domestic USBi devices do not support 1.8V I0).

3. The supply voltage for Pin B is selectable: VIN = 3.3V or 5V (USBi uses 5V); the supply voltage for Pin A is generated by LDOU2.
